Automating Cisco 4006 switch configuration

[sasj0e]

Hi,
Is it possible to automate the process of configuring the Cisco catalyst 4006 with sup II?
For example...
writing a batch file in a windows system to perform a set of tasks.
Say
Telnet to Cisco catalyst.
1.entering loging password
2.entering "enable"
3.entering password
4. sh port
5.sh vlan
6.set vlan 3
.....etc one after the other.
Cant we do this by writing a batch file or similar..to perform the tasks one after the other..?
Pls let me know on this.
Regards,
Sas

It's very easy. You instruct the script to send a string then capture the results until a certain string. I have written a Python script that opens a list of cisco devices, issues a command and records the results in a file. There's no limit to what you can do as long as you follow the send/expect sequence.
